A scientifically perfect formula is ineffective if you cannot enjoy consuming it. Taste is a highly personal but critical factor; a pleasant flavor encourages adequate hydration and consistent use. The mouthfeel—whether it is light and refreshing or more substantial—also affects the drinking experience during different intensities of activity. From a practical standpoint, consider the packaging. Is it a convenient ready-to-drink bottle, or a portable powder or tablet that can be mixed on the go? Ease of use, portability, and the ability to control concentration (in the case of powders) add significant value to the overall user experience.
